OK. Since my other trick, “The Cork off the Bottle” worked so well, I’m going to show you another trick that I believe is very cool. And you need some ketchup from one of those fast food restaurants, a plastic bottle with water inside, and let me show you. Put the ketchup inside the bottle. Then you close the bottle and watch!
Do you like the trick? Well, actually, it’s a very simple trick, and all you have to do is take a ketchup that doesn’t have much air inside. It has to barely float. You put this ketchup inside a plastic bottle with water inside, you close the bottle, and when it’s inside, all you have to do is make pressure with two fingers on the bottle. And watch what happens. I make pressure, and it goes to the bottom. I let it go, and it goes to the top. And if I barely touch the bottle, I can make it go right in the middle and make it stop right there.
It’s a very cool trick, and you can impress a lot of people with this. But you have to remember that the ketchup inside has to barely float. If there is too much air inside the ketchup, you won’t be able to do this trick.
